# Stasis idle manager configuration for Moonarch
# Manages screen dimming, DPMS, lock, and suspend timers

@description "Idle management for Moonarch (Niri + gtklock)"

# TIMEOUTS ARE CUMULATIVE, NOT ABSOLUTE.
#
# Each `timeout` counts from the moment the *previous* step in the same block
# fired, not from the last input event. Only the first step measures raw idle
# time. Verified against a running daemon: with `dpms 120` followed by
# `lock_screen 180`, dpms fired at 18:43:30 and the lock at 18:46:31 -- 181
# seconds later, not 60.
#
# This file previously carried the upstream template's numbers while reading
# them as absolute. The result was a screen that went dark after 2 minutes when
# 6 were intended, and a `brightness 300` step behind a `dpms 120` step that
# could never run, because the display was already off when its turn came.
#
# Step order inside a block is execution order. Lock before DPMS, so the
# session is already secured when the display shuts off, and the display then
# stays off instead of being lit again to show the locker.

default:
  # monitor_media: detect active media via PipeWire/PulseAudio sink-inputs
  # (pactl), not MPRIS. Non-browser players (mpv, vlc, ...) are counted and
  # inhibit idle. Browser audio is excluded by design; browser idle-inhibit is
  # expected via D-Bus (enable_dbus_inhibit), which Waterfox/Firefox only send
  # in fullscreen -- so windowed browser video is NOT caught by stasis.
  # ignore_remote_media false: also count remote players (Spotify-remote,
  # KDEConnect, Chromecast); has no effect on windowed browser video.
  monitor_media true
  ignore_remote_media false

  # Both empty on purpose: nothing here should keep the machine awake beyond
  # what inhibit_apps already covers. They are set rather than omitted because
  # stasis discards any config missing a knob its own template carries, backing
  # it up and starting over from that template.

  # Every binary named in a command below has to be on the PATH of the unit
  # that starts stasis -- stasis does not run the actions through a login
  # shell, so /etc/profile never applies. A missing binary fails silently: the
  # step is logged as started, exits immediately, and the plan stops there.
  # In moonix that PATH lives in modules/services.nix.

  # Desktop plan (machines without a battery)
  #
  # These blocks sit directly under `default:` on purpose: stasis builds the
  # desktop plan from exactly those, with the ac:/battery: containers excluded
  # (src/config/mod.rs, parse_plan_block "default"). A machine whose chassis
  # reports no battery gets PlanSource::Desktop, and select_plan_source only
  # ever falls back *onto* the desktop plan, never from it onto ac: -- so with
  # the action blocks living in ac:/battery: alone, a desktop ran a plan of
  # disabled steps: no DPMS, no lock, "waiting for idle" forever.
  #
  # Only brightness is left out: brightnessctl drives an internal panel, and
  # external monitors need DDC/CI, which it does not speak. /sys/class/backlight
  # is empty on a desktop, so the step would be a no-op.
